Ergonomical flippers for swimming or diving

ABSTRACT

Ergoniomical flippers for swimming or diving include a nautical shoe and a fin forming a single part of the same material. The fin extends from the sole of the nautical shoe with an inclination of about 45° with respect to the front area of the sole or tip and from an intermediary position between the middle of the sole and the tip. It is also provided with a triangular prismatic reinforcement both at the front and rear areas respectively of the junction between the sole and the flipper or fin, thereby forming a single part. Also, minor sides of each reinforcement are in contact with the sole and the fin.

OBJECT OF THE INVENTION

This invention relates to ergonomical flippers for swimming or diving which provide essential innovative characteristics with respect to the means known and used in the state of the art.

Generally the ergonomical flippers for swimming or diving that are the object of this invention comprise conventional nautical shoes, with the novelty that the fins form a certain angle with respect to the sole of the corresponding nautical shoe and form a single part therewith.

In particular, the ergonomical flippers for swimming or diving that are the object of this invention, are formed by an extension of the actual sole of the nautical shoe that forms a front angle therewith of approximately 45°.

FIELD OF THE APPLICATION

The ergonomical flippers for swimming or diving that are the object of this invention, are applicable to both the professional sport and recreational swimming material industry.

STATE OF THE ART

Currently there is a great variety of flippers for swimming or diving on the market, all comprised generally of a nautical shoe the sole of which extends in the front area thereof into the corresponding fin, which is coplanar to said sole of the nautical shoe.

With this type of known flippers, when swimming or diving and making the corresponding leg movements, the force that the water exerts on the flippers, forces the foot's natural 90° angle vis-à-vis the leg, to a position of virtually 180° where the foot and the leg are virtually aligned, which puts a constant strain on the human anatomy, resulting in various aches and pains in feet, legs, tendons, muscles, circulation, etc.

DESCRIPTION OF THE INVENTION

This invention consists of ergonomical flippers for swimming or diving, the structure of which, when swimming, only allows the leg and foot to be moved in an angular fashion just as when walking normally, in other words the foot only moves at an angle of 45° with respect to the leg, which inevitably avoids the aches and pains caused by state of the art flippers.

In particular to achieve these advantages, the ergonomical flippers for swimming or diving of this invention are formed by an extension of the nautical shoe, from the sole thereof and at an angle of 45° with respect to the front part thereof, whereby with a simple 45° movement of the foot with respect to the leg, the flippers will lie at 180° vis-à-vis the leg, while the foot has only moved 45° instead of 90°, which is the degree the foot has to move with state of the art flippers.

All this will be explained in greater detail throughout the following description of this specification.

BRIEF DESCRIPTION OF THE DRAWINGS

The description of the object of the invention is based on the accompanying drawings, which represent a non-limiting example of a preferred embodiment thereof, and in which:

The first figure corresponds to a longitudinal sectional view of an ergonomical fin for swimming or diving that is the object of this invention, arranged as an extension of the actual material of the sole of the nautical shoe and forming an angle of approximately 45° with respect to the front area of the sole or tip.

The second figure represents a longitudinal sectional view of an ergonomical fin for swimming or diving that is the object of this invention, with reinforcements in the front and rear areas where it is joined to the sole.

Lastly the third figure corresponds to a longitudinal sectional view of an ergonomical fin for swimming or diving that is the object of this invention, with the reinforcements in the front and rear areas covering the full extension of the sole of the nautical shoe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT OF THE INVENTION

The following detailed description of the preferred embodiment of the invention is based on the attached drawings, where corresponding or similar parts have been assigned the same reference numbers throughout the figures.

As can be seen in the accompanying drawings, the ergonomical flippers for swimming or diving that are the object of this invention, comprise a nautical shoe (1) and a fin (2) forming a single part of the same material, which extends from the sole (3) in an intermediary position between the middle of the sole and the tip.

Fin (2) is inclined at approximately 45° with respect to the front area of sole (3). Fin (2) in one of the preferred embodiments has reinforcements (4) and (5) in the front and rear areas respectively of the junction between sole (3) and fin (2).

In another of the preferred embodiments, fin (2) and reinforcements (6) and (7) form a single part together with nautical shoe (1), with front reinforcement (6) extending from the tip to the front of fin (2) and rear reinforcement (7) extending from the rear area of sole (3) to the rear area of fin (2), there being determined between reinforcements (6) and (7) and fin (2), a space (8) without any material.

Via this structure of ergonomic flippers for swimming or diving that are the object of the invention, the corresponding movements of the swimmer or diver cause fin (2) to lie at 180° with respect to the leg, i.e. aligned as an extension thereof, via a simple 45° movement of the foot, in relation to its normal position with respect to the leg, therefore avoiding an exertion of the foot's movements in relation to the leg as this is the foot's normal walking movement with respect to the leg. The arrangement of reinforcements (4) and (5) or (6) and (7) make fin (2) more rigid.

No further description is considered necessary for a a person skilled in the art to understand the scope thereof and perform a practical embodiment.

However and since only three preferred embodiments of the object of the invention have been described above, it is obvious that numerous modifications can be made to the essential nature of the invention, without this actually affecting the invention. Said modifications can affect, in particular, the shape of the object, its dimensions, size and manufacturing material, and its essential features are described in the following claims. 

1. Ergonomical flippers for swimming or diving, comprising: a nautical shoe having a sole with a front area, and a fin forming a single piece with the fin and being of a same material as the fin, the fin extending from the sole of the nautical shoe with an inclination of about 45° with respect to the front area of the sole and extending from an intermediary position of the sole between a middle of the sole and a tip of the sole.
 2. Ergonomical flippers for swimming or diving according to claim 1, wherein the fin is provided with respective prismatic triangular reinforcements in front and rear areas respectively of a junction between the sole and the fin, with smaller faces of each reinforcement being in contact with the sole and the fin.
 3. Ergonomical flippers for swimming and diving according to claim 1, wherein the fin has front and rear reinforcements forming a single piece with the fin and the nautical shoe, with the front reinforcement extending from the tip to a front area of the fin and the rear reinforcement extending from a rear part of the sole to the a rear part of the fin, such that there is a space without any material between the two reinforcements.
